Definitions

  • the present invention relates to a device and a technique for manufacturing fiber-reinforced plastic (FRP) products by affixing a fiber bundle that has been impregnated with a resin in advance to an affixing surface.
  • FRP fiber-reinforced plastic
  • FRP fiber-reinforced plastic
  • AFP auto fiber placement
  • ATL auto tape layup
  • a manufacturing method in which fiber bundles and/or the affixing surface is at least heated by a heating means and the fiber bundles are successively affixed to the affixing surface shall be referred to collectively as ATL, and the device used for this (fiber bundle affixing device) as an ATL device.
  • the usual practice is to make use of an ATL head (affixing head) that affixes at least temporarily hold at least a part of the fiber bundle, moves relative to the affixing surface along the affixation path of the fiber bundle while affixing the fiber bundles under heating and/or pressure.
  • ATL head affixing head
  • the heating means here is very often a non-contact heating means such as a laser or an infrared lamp.
  • a pressing member such as a roller or a shoe that sandwiches the fiber bundle between itself and the affixing surface while pressing the fiber bundle in the normal direction of the affixing surface.
  • the affixing surface is preferably a free-form surface, and therefore the operation of the ATL head often needs to have a three-dimensional freedom (translation and rotation). Therefore, the ATL head is often attached to an articulated robot, or to a so-called gantry structure that combines orthogonal and rotational movement systems.
  • the fiber bundle to be affixed is usually supplied in a form that is wound on a bobbin, and in the ATL device, a mechanism for unwinding the fiber bundles from the bobbin (referred to as a creel) is essential.
  • ATL devices can be classified into two main types.
  • the unwinding mechanism is mounted on the ATL head itself (this will hereinafter be referred to as a mounted type, an example of which is shown in FIG. 6 ).
  • the fiber bundles are played out from a fixed (stationary) unwinding mechanism and fed to the ATL head along the conveyance path (known as a yarn path) (hereinafter referred to as a stationary type, an example of which is shown in FIG. 7 ).
  • the usual practice is such that after a predetermined length of the continuous fiber bundle unwound from the bobbin has been affixed to the affixing surface, the fiber bundle is cut near the affixed rear end to complete the affixing operation. Therefore, there is normally a fiber bundle cutting means in the ATL head.
  • the ATL head 31 itself comprises an unwinding mechanism 32 , and a bobbin 33 is located inside the ATL head 31 , an advantage of which is that there is no need for a complex conveyance system (yarn path 45 ), in contrast to a stationary type of ATL device 40 (see FIGS. 6 and 7 ).
  • an ATL head undergoes translational movement on the affixing surface in all directions according to the affixing operation, and itself swings (rotates or revolves) according to the normal direction of the affixing surface. Therefore, it is necessary to supply the fiber bundle D from the stationary unwinding mechanism 42 (creel) to the ATL head 43 that moves and rotates in all directions. Furthermore, since the fiber bundle D is in the form of a tape, there is a limit to how far the fiber bundle D can be twisted along the yarn path 45 , so a problem is that the fiber bundle D must be supplied to the ATL head 43 while still in the form of a tape, without being twisted more than one rotation, and this makes the yarn path 45 longer and more complicated.
  • the prepreg tape itself has a sticky, tacky surface, and it is preferable to minimize contact with the conveying member, sliding, and so forth as much as possible, so a problem is that the structure of the yarn path 45 and the conveying member becomes more complicated.
  • the ATL head 31 itself carries the unwinding mechanism 32 , it often ends up being large and heavy. Therefore, the articulated robot 35 or gantry on which the ATL head 31 is mounted also need to be large and highly rigid, and this drives up the overall cost of the ATL device 30 . Also, there is a limit to the fiber bundle (bobbin 33 ) that can be mounted on the ATL head 31 , and thread replacement (bobbin replacement) and so forth tend to be needed more frequently than with a stationary type. This leads to a problem in that the operating rate of the ATL device is decreased as a production device.
  • the ATL head 31 is equipped with a heating means for the fiber bundle and/or the affixing surface.
  • a radiant heat source such as an infrared lamp 8 , a forced air heater, or the like is often used as the heating means. These devices themselves also usually generate considerable heat during their operation.
  • a laser is also sometimes used as a heat source, in which case the laser oscillating tube itself is usually provided on the outside of the ATL head 31 , and the laser light is guided by an optical fiber or the like to the ATL head 31 . For this reason, although less heat is generated inside the ATL head 31 than with a radiant heat source or forced air heater, heat is still generated by the lenses, reflectors, and other such optical members.
  • the heat from the heating source will gradually build up in the ATL head 31 as the affixing operation proceeds, that is, in the course of the heating operation of the heating source, and this can result in a phenomenon whereby the ATL head 31 itself is heated and rises in temperature.
  • the fiber bundle E that is mounted on the ATL head 31 but has not yet been affixed is affected by this heat.
  • the fiber bundle E is a thermosetting prepreg tape
  • the adhesiveness and tackiness of the prepreg tape itself may be further promoted by temperature.
  • This causes a problem in that slidability along the conveyance path decreases from the unwinding mechanism 32 up until the affixing, which raises the conveyance resistance, and if this becomes very pronounced, the fiber bundle may adhere to the conveyance path and cause a conveyance failure.
  • unwinding from the unwinding mechanism 32 may not proceed properly, and the heating is excessive, some of the impregnating resin, which is thermosetting, will start curing, and this can alter and degrade the characteristics of the prepreg tape.
  • fouling of the surface of the conveyance path due to impregnating resin that has fallen off may also be promoted, among other such problems.
  • thermosetting prepreg tape is discussed above, but even in the case of a fiber bundle impregnated with a thermoplastic resin (hereinafter referred to as a UD tape for convenience), problems attributable to temperature may still occur.
  • a thermoplastic resin hereinafter referred to as a UD tape for convenience
  • thermoplastic resin that impregnate a UD tape is solid at room temperature, and therefore the surface thereof is not usually sticky or tacky as is a prepreg tape.
  • PP polypropylene
  • PA polyamide
  • PPS polyphenylene sulfide
  • the present invention is a fiber bundle affixing device having an affixing head that affixes fiber bundles that have been cut in advance to a predetermined length, one by one to an affixing surface under heating and/or pressure, wherein the affixing head has at least a heating means for heating the fiber bundles and/or the affixing surface, and a holding and conveyance means for holding and/or conveying just one fiber bundle, and during the operation of affixing the fiber bundles by the affixing head, only the fiber bundle being affixed by the affixing head is held and/or conveyed by the holding and conveyance means.
  • a fiber bundle affixing device wherein the affixing head is attached to an articulated robot or a gantry structure.
  • a fiber bundle affixing device further comprising a fiber bundle storage means for storing the fiber bundles, and a fiber bundle supply means for supplying the fiber bundles stored in the fiber bundle storage means to the affixing head.
  • the fiber bundle affixing device according to any one of claims 1 to 3 , wherein at least a part of the fiber bundle is impregnated with a resin in advance.
  • a fiber bundle affixing device wherein the fiber bundle includes carbon fibers, and the resin is a thermoplastic resin.
  • the present invention when a fiber bundle that has been cut in advance to a predetermined length, that is, the length to be affixed, is affixed under heating and/or pressure with an ATL head, only the fiber bundle that is undergoing the affixing operation is allowed to be present in the ATL head, so the other fiber bundles do not remain near the heating source in the ATL head for an extended period of time, which reduces the influence of the heat from the heating source.
  • the fiber bundles are cut in advance to a predetermined length and stored in a fiber bundle storage means, and then a fiber bundle supply means supplies the fiber bundles one by one to the ATL head, which makes it possible to avoid the problem of creating a long fiber bundle conveyance path, and the problem of increased size and weight of the ATL head.
